Abstract
A lightweight laminate capable of maintaining mechanical properties while exhibiting excellent flame retardancy, a method for producing the laminate, and a prepreg are described, where the laminate includes fibers; a matrix resin; and a flame-retardant filler and satisfies 0.01<A/B<0.15 under the described conditions where A and B are as defined. The prepreg includes fibers; a matrix resin; and a flame-retardant filler and satisfies 0.01<A/B<0.15 under the described conditions where A and B are as defined.
Claims7
A laminate comprising:
- fibers;
- a matrix resin;
- and
- a flame-retardant filler,
- wherein in a cross section at 45° with respect to a fiber direction, when an area occupied by the flame-retardant filler in the entire cross section at 45° is 100%, an area occupied by the flame-retardant filler in a range of 400 μm from one outermost surface of the laminate is 70% or more, and when a flame-retardant filler area in the range of 400 μm from the outermost surface in the cross section at 45° is A, and a matrix resin area is B, the following relational expression is satisfied:
- 0.01<A/B<0.2.
