    Abstract: The invention relates to the use of a fibre-reinforced composite (K) in a thermoforming process. Moreover, a process for thermoforming a fibre-reinforced composite (K) to a molded body (M) is disclosed, the process comprising at least the following steps: (i) Providing a fibre-reinforced composite (K) as described herein; (ii) Heating the fibre-reinforced composite (K) to a temperature (T3) at which the at least one substantially amorphous matrix polymer composition (B) is substantially softened; (iii) Thermoforming the fibre-reinforced composition (K) in a mold at a mold surface temperature (T4) in order to obtain a molded body (M); (iv) Releasing the molded body (M) from the mold; wherein the mold surface temperature (T4) is ≥50° C.

    IPC: C08J5/04

    Abstract: The invention relates a process for preparing a fibre-reinforced composite (K) comprising the following steps: (a) Providing at least one continuous fibrous reinforcement material (A); (b) Providing at least one matrix polymer composition (B) having melt volume-flow rate (MVR (220/10) according to ISO 1133) of 40 to 70 mL/10 min and a viscosity number VN (according to DIN 53726) of 45 to 75 ml/g; (c) Applying the at least one matrix polymer composition (B) to at least one surface of the at least one continuous fibrous reinforcement material (A) to obtain a layered arrangement; (d) Heating the layered arrangement obtained in step (c) to a first temperature (T1) sufficiently above the glass transition temperature (Tg) of the at least one substantially amorphous matrix polymer composition (B) to obtain a substantially liquid substantially amorphous matrix polymer composition (B); (e) Allowing the substantially liquid matrix polymer composition (B) to impregnate the at least one continuous fibrous reinforcement material (A); (f) Cooling the thus obtained polymer-impregnated continuous fibrous reinforcement material (A) to a second temperature (T2) below the glass transition temperature (Tg) of the at least one substantially amorphous matrix polymer composition (B) in order to obtain a fibre-reinforced composite (K); wherein substantially amorphous matrix polymer composition (B) is a thermoplastic styrene-based substantially amorphous matrix polymer composition (B) and wherein least one of the process steps (d) and/or (e) is carried out at a temperature in the range of 230 to 330° C.

    Abstract: The invention relates to a fibre-reinforced composite (K) comprising: (A) ≥50 wt.-%, based on the total weight of the fibre-reinforced composite (K), of at least one continuous fibrous reinforcement material; and (B) 0 and ≤3 wt.-%, derived from monomer moieties which are appropriate to interact with the surface of the fibrous reinforcement material (A), in particular of repeating units derived from maleic acid anhydride or maleic acid, and wherein less than 10% of the number of the reinforcement fibres present at a fracture surface of the fibre-reinforced composite (K) protrude from the fracture surface with a length of more than 5 times the diameter of the fibre.
